JC Vac & Shampoo Combo problem

[Cal-Redwood]

My Vac combo, the alarm on all the time. I changed out the horn, timer and coin acceptor and still the same failure. I reverse the leads on the horn, the alarm is off and the Vac is working OK but there is no beep tone when inserting coins. Is anyone had this problem before or your advice is greatly appreciated.

I'm guessing it's a swipe n clean vac? If so then the problem is in the pbc board. I have had that happen twice and just last week sent in my pbc board for repair for the same issue. If it is not swipe n clean, then you have something shorting out somewhere sending the constant horn.

Thanks slash007, I think the Vacuum was swipe n clean but now I'm not using the swipe n clean but still has to use the PCB. Where do you send the PCB to repair.

Call Lisa, she can tell you everything you need. She can also send you the schematics for the timer. I have swipe n clean vacs that I am converting over to push button. So you are saying that you can use both the swipe n clean and have push buttons? I was under the impression that I would have to get rid of the swipe n clean.

I have converted my Vac from swipe n clean to push button but have to keep the PCB to make it work. I wish I know or do not have to use the PCB again to make it work. If you convert yours and do not have to use the PCB please let me know.

What did you do to convert to push buttons? Did you just splice a wire from the push button to the wire that activates the vac or shampoo? Wayne at B & C electronics sent me a schematic of how the wiring is for non swipe n clean vacs, but I basically need to figure out how to do it myself or they offer support for a fee. I'm honestly not sure if I would even want to get rid of the keypad if I can keep it working as it works great for the little cc use it gets but mostly for giving out free vac time when there is an issue.

About 2 yrs ago when I take over the Car Wash, the swipe n clean did not function at all. My distributor suggested I get rid of the swipe n clean and switch the vac combo to push button. He ordered a new label for the front door and push swithes. I installed and only removed the key pad but have to keep the PCB to make it work. I wish there is way to get rid of that PCB which will make the Vac work more smoothly and less headache.

Thanks slash007, I replaced the PCB board and that fixed the problem.

Glad it worked out!

You DO NOT need to keep the PBC in order to add push buttons. I just converted one of mine a few minutes ago and removed the pbc and keypad and changed the door. I just left the two harnesses that go to the pbc hanging. If you already added push buttons, then the only thing that will not work after removing the pbc will be the horn. And to fix that it is very simple. You just have to move one wire to another. I just traced the wires from the horn and one of them was already in the correct position and the other jumped over to the pbc (it was a thin brown wire on mine) so I just had to jump that to the thick red/black wire that goes to pin 4 on the timer. Let me know if you need any help.

This is very helpfull and Thank You very much. I'll try it after work today.

Before you try it, there is one more thing you should know. The next day I had a complaint that no foam was coming out of the brush when pushing the button, so I ended up having to also move a wire from liquid solenoid. There are two black wires coming from that solenoid. One attaches to the push button on the handle and the other went to the terminal strip and a white wire was on the other side of the strip. I just had to move it one screw over so that it attached to the black wire on the strip instead. Worked perfectly after that.

Thanks slah007, I had removed the PBC on my VAC Combo and they work fine. Thank again for your help. Thuan.

 

[slash007]

That's great to hear! I'm glad it worked out for you. It is so much better to not have to deal with the PBC if you are not using it. I just wish I had know that before I sent it a couple for repair. Now I have extras since I am pulling them from half the vacs.

Oop, didn't see your post and it happen exactly like you said. I removed the PCB last Saturday and a few minutes after I finished. One customer use the carpet cleaning and the soap solution was not coming out when he push the button. I thought something else was going wrong again but I was busy so didn't have a chance to look at it yet.
So I need to connect the white wire to one of the black wire (the one that connected on the terminal) as you mentioned above.
Is that same way with the vac & fragent?
Thanks

No, you need to connect the black wire from the liquid solenoid to the black wire on the terminal. There are two black wires coming from the solenoid. One goes to the push button on the handle, the other goes to the terminal strip and connects to a white wire. I just move the black wire from the solenoid over one spot on the terminal so that it connected to the black wires instead of the white.

I haven't tried a Frag/Vac yet as I am waiting on some new doors, but the frag buttons are wired the same whether there is a PBC or not, so you shouldn't have to make any changes for those other than the horn wire. Just on the Sham/Vac.
